When I only display and edit drum tracks (each assigned a drum map) in the PRV, I want to be able to hide (not minimize) the Notes pane because it's absolutely unnecessary. The pane shows up like a jerk when I hit Shift+D to maximize the MultiDock. The pane's ceiling blocks me from dragging up the ceiling of the Controller pane further (so I have to first drag up the ceiling of the Notes pane).
 
Please. What's the point of displaying a pane that contains no data?

Absolutely agree!

PRV is central to so many things.   Please, CW, hire a GUI programmer just for this, and one who can deal with a drum map, a midi track, multiple midi tracks, multiple controllers on multiple midi tracks, a midi track plus a drum map ...

You forgot to vote, William.

Lol.  I didn't forget, I just don't fully agree with the OP.   So abstaining seemed the best course.   But improvements of any sort in PRV are very welcome.

Maybe you didn't know this, but when you don't fully agree (but somewhat agree), you can give 4 stars, and that would be helpful.
